| 摘 要： | 根据2008年9月在闽江口水域和2010年8月在椒江口水域的调查资料,对两个河口浮游动物的种类组成、生态类群、优势种和生态适应差异进行分析比较,探讨夏季闽江口海域和椒江口海域浮游动物群落结构的区别及其组成受水团变化的影响。研究结果表明:夏季,椒江口受上升流的影响出现13个暖温带种,导致椒江口(44)水域浮游动物种类数要大于闽江口(36);闽江口海域夏季主要受到台湾暖流的影响,6个优势种全部为亚热带种,椒江口有7个优势种,包括4个亚热带种和3个暖温带种;从适温性上看,闽江口和椒江口均主要以亚热带种为主,椒江口由于上升流的原因出现较多数量的暖温带种,从适盐性上看,椒江口主要以近海种为主,闽江口主要以外海种为主,这是闽江口和椒江口浮游动物生态类群的主要差异;闽江口浮游动物群落结构主要受到台湾暖流和沿岸流的影响,而椒江口主要受到浙江近海上升流和沿岸流的影响,通过对两个河口群落结构的比较和生态适应差异的分析,表明水团是各自浮游动物群落结构的形成过程中的一个重要因素。

| Abstract: | Based on the zooplankton samples from stations in the Minjiang River Estuary in September 2008 and Jiaojiang River Estuary in August 2010. The species composition, eco-groups, dominant species and differences in ecological adaptation of the zooplankton in two area were analyzed and compared. The differences in community structure of Minjiang River Estuary and Jiaojiang River Estuary and the impact of variation of water masses on these ecological characters was discussed. The results indicated that 13 warm temperate speices were founded in Jiaojiang River Estuary, because it was strongly influenced by the upwelling, it was the reason that the species number of Jiaojiang River Estuary (44) was more than Minjiang River Estuary(36). The 6 dominant species of Minjiang River Estuary were mainly subtropical species because it was influenced by Taiwan Warm Current in summer, Jiaojiang River Estuary had 7 dominant species which included 4 subtropical species and 3 warm temperate speices. According to the point of optimum temperature, both Minjiang River Estuary and Jiaojiang River Estuary were mainly consisted by subtropical species, some warm temperate speices were also founded in Jiaojiang River Estuary because of the reason of upwelling. According to the point of optimum Salinity, Jiaojiang River Estuary was mainly consisted by nearshore species, Minjiang River Estuary was mainly consisted by offshore species, which was the major difference of the ecological groups of two waters. The community structure of zooplankton in Minjiang River Estuary were strongly influenced by the coastal curent and the Taiwan Warm Curent, but Jiaojiang River Estuary was mainly affected by the coastal current and the upwelling. Comparison and analysis of the community structure of zooplankton between Minjiang River Estuary and Jiaojiang River Estuary indicated that the water mass is an important factor in formation of the community. |
